A 3D rendering method, device and electronic device for cigarette packaging based on WebGL

Abstract

The present invention discloses a 3D rendering method, device and electronic device for cigarette packaging based on WebGL, the method comprising receiving a graphic design file, processing the graphic design file based on printing process step information in a printing process database, so as to layer the design structure in the graphic design file according to the printing process step information; parsing each layered design structure, generating 3D materials for each layered design structure based on the printing process step information; loading a 3D model corresponding to the graphic design file, and mapping and rendering each 3D material layer by layer on the 3D model according to the process step sequence between the printing process step information. The present invention achieves that each layer corresponds to a layer of geometric structure, so as to simulate a real layered printing process. While ensuring high-quality rendering results, the texture data in the process comes directly from the original graphic design file, and there is no need to make additional high-resolution textures, eliminating the hidden danger of front-end collapse and improving overall work efficiency.
